Perfusion Systems: Single-Use vs Reusable Setup
If you run perfusion for cultivated meat, the setup choice usually comes down to one question: where do you want the main burden to sit - in disposable flow paths...

Most products require no additional agreements. Cell lines and certain biological materials require a Material Transfer Agreement (MTA) on first purchase from each supplier. We handle this digitally - both parties sign online before shipment. Subsequent orders from the same supplier proceed immediately.
XCeLL Factor™ Recombinant FGF2 Gallus from Cell Culture Collective is a high-purity, heparin-binding recombinant protein engineered to support cell proliferation, migration, stem cell expansion, and tissue regeneration in avian cell culture systems. Produced via an E. coli expression system, this chemically defined growth factor plays an essential role in maintaining primary cell lines and satellite cells, making it an excellent component for cultivated meat research and serum-free formulation strategies.
The protein features an amino acid length of 189 AA (with His tag) and an estimated molecular weight of ~20.7 kDa. It undergoes rigorous quality control to deliver >95% purity as evaluated by SDS-PAGE, an endotoxin level of <0.1 EU/µg, and a 0.2 µm sterile-filtered rating. In functional validation assays utilizing NIH-3T3 fibroblast proliferation, it demonstrates dose-dependent activity with an ED50 of ≤1 ng/mL.
Available in flexible lyophilized or liquid formats under catalog number XCF-FGF-003, the protein is shipped on dry ice or gel packs. For long-term stability, lyophilized protein should be stored between -20°C and -80°C. Reconstitution in sterile water or PBS to a concentration of 0.1–0.5 mg/mL allows stable storage at 2–8°C for up to one week, or long-term storage in frozen aliquots at -20°C. This product is intended for research use only.

Cell Line SpecificityAvian
Cellag Bio is the structured intelligence layer for cultivated meat R&D — scattered published research distilled into decision-ready records: what worked, what failed, the likely cause, and what to do instead. Before committing budget to a medium, reagent, or cell line, check the evidence behind it: real experimental outcomes and failure modes, not marketing claims.
Search by media, reagent, cell line or species (e.g. "Beefy-9" or "B8") to find the records that use it.
